GNOME Bugzilla – Bug 527954
PDF printer rendering does not display correctly in Adobe Reader
Last modified: 2009-03-29 21:11:40 UTC
Please describe the problem: I attempted to output to PDF file, with the pseudo PDF Print device, some Sudoku puzzles from the Gnome Sudoku app. I printed two puzzles per page and everything seemed to display fine with Evince. However, when viewed on a Windows platform using Adobe Reader 8 (one would presume to be the gold standard of PDF viewing) the top puzzle displays fine but the bottom one of each page displays an empty grid. Steps to reproduce: Steps to Reproduce: 1. Open Sudoku in Gnome and print 10 puzzles with two to a page 2. Open in Evince 3. Open in Adobe Reader 8 on Windows Actual results: Actual results: Open in Evince displays fine Open in Adobe Reader on Windows only displays the top puzzle numbers and not the bottom ones. Expected results: Expected results: The PDF should display correctly regardless of platform/reader. That is the selling point of the PDF format. Does this happen every time? Always Other information: This issue may just be the Sudoku app but it might point to a deeper rendering issue within Cairo and this is a nice small test case. Strangely enough, it appears that the numbers for the bottom puzzle are there, they may just be rendering in white on a white background. If I open a page of the PDF with the new Inkscape 0.46 on Windows it shows up fine. If I then re-save that single page the seconds puzzle shows up fine in Adobe Reader. So whatever Inkscape (which I believe also uses Cairo) does in Windows corrects the problem. This was tested with Version: Adobe Reader 8 Rawhide LiveCD snapshot 20080404 cairo 1.5.16-1.fc9 also upgraded to current rawhide of cairo 1.6.4-1.fc9 and restarted X with the same effect. I will attach the two PDF files generated. Submitted upstream at bug triage request. Original bug was reported here: https://bugzilla.redhat.com/show_bug.cgi?id=441341
Created attachment 109202 [details] Output of Sudoku with cairo 1.5.16 installed
Created attachment 109203 [details] Output of Sudoku with cairo upgraded to 1.6.4
Switching this to gnome-games as that seems to be where the issue is according to downstream analysis by John (J5) Palmieri at https://bugzilla.redhat.com/show_bug.cgi?id=441341#c10 In a nutshell, Sudoku is using the old depreciated gnome-print (not cairo as I previously thought) and should be upgraded to use cairo.
sudoku has been ported to gtk print in 2.27. Thanks for reporting the issue
